Application filed January 4, 1915. Serial No. 407.

To all w/imnit may concern: Y

Be it known that I, James A. DAY, a citizen of the United States, residing at Taze well, in the county of Claiborne and State of Tennessee, have invented certain new anduset'ul'Improven'ients in: Disintegrators, of which the following is a specification.

This invention relates to machines for disintegrating or pulverizing lime-stone and other materials, and more particularly a machine of this kind in whichthe material is subjected to the action of a series of'rap-j idly/revolving heaters in a cylindrical. casing.

The invention has for its object to pro-- ride, in a inachiue df the kind stated, a novel and iu'iproved (construction and arrangement of heaters whereby a maximum eliiciency is obtained, as will be described hereinafter. i in order that the invention may be better understood, reference is had to tl1 5l((30m; panying drawing,- in which- Figure l is a cross sectionof the machine on the line 11 of Fig. 2, and Fig. 2 is a longitudinal section thereof on the line 2 of Fig. 1.

Referring specifically to the drawings, the cylindrical casing of the machine is' composed of end plates 5, and cross bars 6 and a grating 7 extending between said plates. In the inner faces of the end plates are grooves in which the ends of the cross bars and the grating seat, and said plates are connected by cross bolts 8, the outer edge of the plates having lugs or ears to receive the bolts, whereby the latter are located outside the p'arts'il and 7. Upon tightening up the nuts-5) on one end of the bolts, the parts 5, (3 and 7 are securely clan'iped together. The two bolts at the bottom of the casing also serve to secure the casing to av base composed of longitudinal sills l0 connected by cross bars 11 and cross bolts 12.

The inner faces of the crossbars 6 are roughened or corrugated.- The grating his composed ot',. a series of cross bars of the right length .to fit between the end plates 5, and properly spaced and keyed in soened by teeth or corrugations-$16,

and-heavier'than the inner, one. Both heaters are hung-on thesame' rod 13, the

inner heater hangin inside'tho outer one. i

The working face 0 each beater is roughin the shape of pyramldal, iprotuherances .which gives the heaters the breaking and crushing capacityof a large. umber of small ham-I- rners, but with the weight and power of a large one. site sides of the chos s bars 6, in view of which it will beseen; that the bars may be reversed if the protiiherances on one side are dulled or worn oii. The heaters hang loose on the rodsfand they ares aced so as to give each a 'free and indepen ent swing ing action. The inturned ends of the heat ers serve as shanks to support the heaters on the rods, the rods passing through said shanks. The smaller or inner heater is designed tooperate. on the smaller lumps ofmaterialwhich often, when the mate- The protuherances' are on oppoby relievingthe strain on the outer beater,'

and greatelv increasing the crushing or grinding action.

The rods 15 on which the heatersl l and 15 are hung are carried by laterally s iaced disks 17 between which latter the ro s extend and to which they are'made fast; The disks are carried by a shaft 18 on which they are made fast, said shaftheing provided with a suitabledrivepulley 19 and I a balance \vheel 20. The drive pulley will 'be connected to a suitable sourceoi power.

In the end plates 5 of thecasing are large I circular openings 21 to permit insertion of the disks 1'? and the parts carried thereb These openings are closed by removal) e cover plates 22 having bearings 23.0n the outside forthe shaft 18.

At the top of the casing, toone side there'- of, is an inlet 24 for the material to be crushed or ground, said inlet being provided 'witha feed hopper 25, which is bolted to the end plates 5. t will be noted that from the inlet 24 to the grating 7 the corrugated crushing surface of the casing formed by the parts 6 is eccentric to the circle described by the free ends of the heaters when they are in motion, and spaced from the heaters a sufficient distance to accommodate the material.

I claim In a disintegrator, a longitudinal bar pivotuily and revoiubly mounted, and provided on opposite sides with pyramidal protuberances extending in a row throughout the entire length of the her, said protuberances forming rows of integrally connected hammers on opposite sides of the bar.

In testimon whereof I affix my signature in presence 0 two witnesses.
